Abstract Efficient carrier injection at metal–semiconductor interfaces is essential for probing intrinsic electronic properties and enabling high-performance devices. Thinning the Schottky barrier via contact doping is a cornerstone strategy in semiconductor technology for minimizing contact resistance (Rc).

Abstract Van der Waals materials display rich structural polymorphs with distinct physical properties. An atomistic understanding of the phase-transition dynamics, propagation pathway and associated evolution of physical properties is essential for capturing their potential in practical technologies. However, direct visualization of the rapid phase-transition process is fundamentally challenging due to the inherent trade-offs among atomic resolution, field of view and imaging frame rate.

Abstract Nonlinear optical processing of ambient natural light is highly desired for computational imaging and sensing. Strong optical nonlinear response under weak broadband incoherent light is essential for this purpose.
